To all whom it mag/concern.'

:se-it known'that r,` ELMER Howmwrt- Lanus, a citizen of the United States, and

resident of Monessen, in the county of Westmoreland and State vof Pennsylvania, have invented certain new' and useful Im revements in Storage Batteries, ci which t e fol- This invention relates to improvements in storage batteries and it consists of the constructions, combinations and Aarrangements herein described and claimed. f

' An object of the invention is to provide a spacer to be attached to each of the positive plates of a storage battery, its function being to hold the plate spaced from the bottom of the jar and to rovide room forthe accumulation of active material that falls :from

l the following specification, reference. being had to the accompanying drawing in which z.

Another object of the invention isto provide an improved separator to be `used between plates. y Other objects and advantages appear' in Figu 1 is a perspective view of a positive storage battery plate showing the spacer attached.

Figure 2 is an end eleva-tion of a number*- of positive and negative lates illustrating the use of both slpacers an separators.v

Figure 4 is a detail horizontal section o n the line 4.--4 of Fig. 1.

one of the positive plllate spacers. 'As is commonly own a storage battery contains a plurality of plates 1 and 2 ofrespectively positive and ne tive sign. These plates are ordinarily of t e Faure'type, m

.f y which the active material 3 is a plied 1n the v grids `while in paste form.

1s material falls out from time to time, particularly from the positive plates, accumulating at the bottom of the jar or container 4 (Fig. 2)

The spacers 5 are slipped upon thebottom edges of the positive plates l to hold them an appropriate distance `from the jar bottom. Active material collecting between plates must rea-ch considerable proportions before any damage by short-circuiting is likely to occur.

A plurality of slotted headsr occur along the bar 7 (Fig. 5) one ateach end and one 1n the center. Obviously the distribution may be otherwise. .Tlie heads extend Vabove the bar 7 and the slots in the heads begin at the top surface-of the bar. The top 'of the bar-V constitutes the bottom of the slots, and' the width of the slots equals the thickness of the b ar 7. This causes the sides'8 of the heads to stand out from the bar producing channels intowhich the falling active material candrop.: The outstanding portions of the iaads provide lateral spacers which `keep e coming buckled (Figs.v1,.2 and 3).

plates from shortlcircuiting when be.

In manufacture the spacer isfformed from i a 'single piece of rubber or other insulating material. lvThe depressions lbetween the heads 6 are either cut or molded in.

Useis also made of a'. novel form of se arator 9. The separator' is made of a Y in plate of wood, grooved-at 10 to leave outstanding ribs 11. The upri ht grooves co-- act in function with that of t e` spacer chan- -ne'ls'to the extent that they permit passage of the falling active material.

-As shown 1n Figs. 2 and 3 these arators 9' CI) come to the to of the heads 6 of t e spacers 5 and not to t e bottom of the plates themselves as is usual in storage batteries. use, the spacers 5 and se arators 9 areassembled substantiall vasin Figs. 2 and. 3.

.The1 bottom edges o the positiveand ne ative plates 1 and 2 are about even.

sides 'ofthe slotted heads 6 extend up the sides of the positive plates 1 and serve as lateral spacers between positive and negative ',1 n

The separators-9 extend down to the top of the heads 6. insuring that the various ,plates shall be kept apart. The grooves 10 run vertically, and as activey material falls off of the plates it settles in the channels betwen the s acers.

While t e' construction and of a generally preferred form, obviously modifications and changes ,may be made without departing from the spirit of the in- Y vention or scope of the claims.

I claim: 1. In combination with thel plate of. a storage battery, a spacer comprising a bar extending along the bottom edge of the asr arrangement of the improved spacer and separator is that plate to support it above the bottom of a bacv tery container, and heads on the bar having slots in which the edge of the plate is fitted, said heads being in outstanding relationship to the sides of the plate and bar providing channels when two or more specand being slotted downwardly to the top of the bar the width of the slots being equal bo the thickness of `the ber, said heads there- .fore standing out' from the sides of the bar `folming channels when two or more spaeg-L;

' ers are assembled. y v

.3. In` combination with a plurality ofl 'L storage battery plaies, spaces ai: the bottom edges of alternate ones of ille plates, bends on said bars being slotted so receive seid plates and rovlde lateral spacers between, ad}o1n1ng p etes preventing sliot-elnculting of plates upon buckling end providing chen--l nels for the collection of falling active me'zeria-l, and separators extending. between the plates upward from said heads being grooved to communica-te with said channels to oonduot said falling material thereinto.
